Subject: Re: [Neo4j] Getting existing Indexs By Java

Sorry Peter

you know I want convert a Neo4j graph to other databases .

DN: So that is just silly.  Why would anyone want to ever do that?  ;-)

I convert all the component of a Neo4j database to the target. But I missed=
 index item in the target environment. I want to know, Is there any chance =
to convert indexed item to the XML or something else ?

DN: Okay , seriously, there are 6 major classes in Java that work with inde=
xes.
Index<cid:CB3D09EC-41C9-4F33-A0F9-0FB9A5AB0E4C>
IndexHits<cid:5F06BA85-3A76-4680-B9A9-F4FC01E0FF98>
IndexImplementation<cid:AF5B04BF-9FFE-4140-A758-A5DD832C7292>
IndexIterable<cid:734CA358-13EF-4A1C-BBEE-EDF19559230B>
IndexManager<cid:B8802045-7B77-4513-976D-AD2F4173A772>
IndexProvider<cid:8EE1BC97-3231-47F2-A3A4-5E205215BDF3>


I think you why you want, the INdexManager has a lot of methods worth explo=
ring.  Whoever designed this class clearly thought of your use case.  I wil=
l provide a caveat however.  I may have misunderstood your request.  If not=
, IndexManager has a method nodeIndexNames<cid:12E4D8AC-F566-4939-AD45-F00C=
3637849E>()
 Which returns an array 9String[]) of all the nodes that are indexes.  One =
returned, you can serialize them into any data format with simple parlous t=
ricks.

Perhaps I did not understand your request?

Duane


for example, imagine we have a graph with two nodes and a relationship.

node 1 :
ID: 1
Property --> Name: Mahdi
Index (PKEY)--> PrimeryKey: 50

node 2:
ID: 2
Property --> Name: Peter
Index (PKEY)--> PrimeryKey: 1


relationship:

Type----> Know
property ---> Since: 2012


so we past this graph to the application and the result something like this

<Node ID=3D1> <Index Name=3D"PKEY" Key=3D"PrimeryKey" Value=3D"50 /> </Node=
>
<Node ID=3D2> <Index Name=3D"PKEY" Key=3D"PrimeryKey" Value=3D"1 /> </Node>


it is much noticeable that we do not have any assumption about index's name=
 , index key .... we just past a graph to the program or function and it re=
turns the : index name  , index key and index value with a specific format

thanks for ur reply

The application must be worked with all graph, so I don't know the informat=
ion is stored as node's property.

Did you store the information also as property on the node?

Otherwise you'd have to use some low level lucene operations to extract it,=
 you can do it manually with the lucene tool called luke,
It can export this data into xml, see:  http://www.getopt.org/luke/
"Export to XML - exports index data and metadata to XML file. This is avail=
able both from the GUI and from the command-line."

I don't have the code at hand to read and use the lucene database format pr=
ogrammatically.

I want to store all nodes that they indexed by corresponding index to other=
 databases. imagine our database has 1 node that it indexed by a index whic=
h is called "PrimaryKey" the key of the index is "PKEY" and the value is "1=
25". we just added this Index by following code:

IndexManager index =3D graphDb.index();
Index<Node> PrimaryKey=3D index.forNodes( "PrimaryKey");
PrimaryKey.add( node1, "PKEY", "125");


so when we pars the databases when we analyse this node , the application m=
ust be fetch all the node index (PrimaryKey) the key of the index (PKEY) an=
d the value (125).
I want to save these information in other databases.

Thanks for ur answer

<br>
so when we pars the databases when we analyse this node , the application m=
ust be fetch all the node index (<font color=3D"#0000ff">PrimaryKey</font>)=
 the key of the index (<font color=3D"#0000ff">PKEY</font>) and the value (=
<font color=3D"#0000ff">125</font>).<br>
I want to save these information in other databases.</div>

<div>Thanks for ur answer&nbsp;</div>
